I bought a bunch of broken units and I'm working through them to try to get a few usable ones! This is the latest one I got working! So, this unit was severely water damaged, but I managed to get the board working... In another body that was cleaner.
So I found a board in a set that I bought off e-bay that was supposed to be "broken", but dude pieced together all his scrap and offloaded a bunch of junk. This was one of 3 boards (out of 4) that booted, but the only one that would actually go into settings (the other 2 crash/freeze. It's weird). But, I digress. After getting this system pieced together and updated, I wanted to check the card slot and couldn't get it to boot any of my DS carts. That's when I finally checked the slot -_-
This thing was WRECKED, but the missing finger is from removing the socket without using the hot air station. I removed the other slot using the HAS, and it was a bit of a pain, due to the giant metal shield. But, after installing the slot I pulled from a dead board (it would only boot sometimes, then die within 5 seconds of loading the UI. It's shedding parts to save the others!)
TL,DR: I pieced this 3DS together with scraps, in a man cave! Yes, I did a C mod, because literally every board had a broken/missing charge port, lol
